  Abstract

In this paper, we propose a sequential motion vector recovery algorithm for H.264 video coding standard. Motion vectors of H.264 video coding standard cover relatively smaller areas than other standard, since motion estimation of H.264 takes place in the fashion of variable block size. Therefore, the correlation of motion vectors between neighboring blocks increases as the block size of motion estimation is lowered. Under the framework of sequential recovery, we introduce a motion vector recovery using α-trimed mean filter. Experimental results show that proposed algorithm is useful in real time video delivery with nearly comparable or better visual quality than previous approaches such as macro block boundary matching and Lagrage interpolation.
